Struts2行動被調用兩次，如果結果類型是json

Question

我有一個Action類有4個操作方法。 所有四個動作操作方法都使用json結果。

通過日誌語句和調試，我已驗證如果我調用操作方法1，操作方法2和3也被調用。但不是4.最後，再次調用操作方法1並生成json結果

如果我將Action方法1的結果類型更改爲帶有jsp位置的缺省調度程序，則只調用操作方法1。 （這是我想要的json結果的行爲） 希望是有道理的。

任何人有任何想法？ 這裏提問這個問題https://stackoverflow.com/questions/3767698/struts2-if-result-type-json-and-method-defined-then-all-methods-get-invoked

但是沒有答案。 如果您需要更多信息，請讓我知道。

    } 

    public List<String> getTheEmailList() { 
     return theEmailList; 
    } 
} 

在這個動作類，我試圖調用ajaxGetGoLiveEmailList，和我所得到的是ajaxGetGoLiveEmailList首先調用，然後ajaxGetChaserEmailList，然後ajaxGetAvailableEntityList，然後ajaxGetGoLiveEmailList被再次調用。跳過ajaxToggleGroupBusinessSubmitted。

如果我改變的ajaxGetGoLiveEmailList結果註釋

results={@Result(location="something.jsp") 

，只有ajaxGetGoLiveEmailList被調用。

當我查看配置瀏覽器時，所有的動作映射都配置正確，指向正確的方法調用。

JSON插件可能會調用所有以「get」開頭的方法，試圖將它們序列化爲輸出。嘗試將你的方法重命名爲別的東西。
